Assessment of Perioperative Transfusion Requirement for Cirrhotic Patients Undergoing Elective Hepatectomy.
The possibility of outlining a risk profile for perioperative blood transfusion of cirrhotic patients submitted to hepatic resection can help to rationalize transfusion policy. ⋯ The risk profile for transfusion of cirrhotic patients undergoing hepatectomy can be better assessed with a model that combines already known clinical factors and hepatic function indexes.

We measured pre-operative hepatic blood flow and postoperative morphine concentration in infants with or without biliary atresia. Thirty-four infants (0-3 months) with biliary atresia undergoing portoenterostomy (Kasai operation) were included and hepatic blood flow was assessed by magnetic resonance imaging before surgery in 12 of them. Sixteen subjects (0-3 months) without liver disease undergoing abdominal or pelvic surgery acted as controls and six of them had hepatic blood flow assessed. ⋯ The median (IQR [range]) morphine concentration after 24 h infusion was 5.9 (4.5-16.4 [2.9-42.2]) ng.ml(-1) and 6.4 (3.2-12.0 [1.9-48.6]) ng.ml(-1) , respectively (p = 0.460). An inverse regression relation was found between the morphine concentration and the hepatic perfusion index (R(2) = 0.519, p = 0.001). Compensatory increases in hepatic arterial blood flow maintain the total hepatic blood flow in infants with biliary atresia.

Targeted muscle reinnervation in the initial management of traumatic upper extremity amputation injury.
Targeted muscle reinnervation (TMR) was initially designed to provide cortical control of upper limb prostheses through a series of novel nerve transfers. Early experience has suggested that TMR may also inhibit symptomatic neuroma formation. We present the first report of TMR performed at the time of a traumatic shoulder disarticulation. ⋯ Eight months post-operatively, the patient demonstrates multiple successful nerve transfers and exhibits no evidence of neuroma pain on clinical exam. Using the Patient Reported Outcomes Measurement Information System (PROMIS), the patient demonstrates minimal pain interference or pain behavior. Targeted muscle reinnervation may be considered in the acute trauma setting to prevent neuroma pain and to prepare patients for myoelectric prostheses in the future.

Orogastric and nasogastric tubes are routinely inserted in anesthetized patients to both reduce the volume of stomach contents and decrease the incidence of postoperative nausea. We present a case of esophageal perforation and subsequent pneumothorax after insertion of an orogastric tube in a patient undergoing routine shoulder arthroscopy.
